BAG- CLEANER.

Specificationof Letters Patent. Patni3d NOV. 15, 1921.

Application filed December 23, 1919. Serial No. 346,906.

To all whom it may coaccrak Be it known that we, (1) Josnrn C. FUL- KERSON and (2) LE ROY B. STUART, citizens of the United States of America, residing at (1), Marion and (2) Cedar Rapids, inthe county of Linn and State of Iowa, have invented certain new and useful Improvements in Bag-Cleaners, of which the following is a specification.

The primary object of the invention is the provision of a cleaner for bags such as those employed for cement, plaster and the like, whereby considerable quantities of the packaged commodity are saved, and the bags are made fit for refilling.

A further object of the invention is to provide means for cleaning'cement bags and the like in a cleanly expeditious manner and at the same time saving the pulverulent material which would otherwise be lost, the device requiring but little attention during operation and being easily and inexpensively installed wherever desired.

With these general objects in view, the invention consists of the novel combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawings and then claimed.

In the drawings forming a part of this application, like reference characters designate corresponding parts throughout the several views, and

Figure 1 is an end elevation of the invention,

Fig. 2 is a vertical transverse sectional view thereof,

Fig. 3 is a perspective view of the forward portion of the same open for the introduction of bags,

Fig. 4; is a front elevation of the bag receiver closed but unlocked and with the locking member illustrated by dotted lines in its normal locking position,

Fig. 5 is a view partly in section and partly in elevation showing the arrangement of the bag engaging floats, and

Fig. 6 is a detail sectional view of a side portion of the bag receiver.

Referring more in detail to the drawings, our invention broadly consists of a cylindrical casing 10 preferably formed of sheet metal with a hinged door 11 in its forward side and having a bag receiving drum 12 trunnioned axially therein adapted for rotation by a motor 13. The drum 12 has closed suit-able bearings 17 centrally of the casing ends 10, with a. sprocket wheel 18 secured v.

the outer projecting end of the shaft 16.

A sprocket chain 19 runs overthe wheel 18 and over arelatively small sprocket 20 upon the drive shaft 21 of the motor, 13 whereby the motor will revolve the drurn'l2 slowly during the bag cleaning operation, the speed of the drum being controlled by regulating the motor 13 in any desiredmanner. The dusty bags such as bags which have been filled with cement, plaster, flour and the like are thrown into the drum 12 when the door 22 ofthe drum is open as illustrated in Fig. 3 of the drawings." This door 22 constitutes a portion of the cylindrical side wall of the drum 12 which wall 23 is foraminous, being in the form of metal screening of a desirable mesh. The door 22 is hinged as at 2% to a strengthening cross brace 25 exteriorly of the drum 12 and longitudinal reciprocating bolts 26 are carried upon the edge strip 27 of the door 22 for reception within perforated lugs 28 oppositely carried by the drum 12. A lever 29 pivoted as at 30 to the strip 27 has the inner ends of the bolts 26 pivoted thereto, and it will be evident that said bolts may be projected or retracted through the guides 31 upon the strip 27 by shifting the lever. The lever 29' has a longitudinal groove 29 on its under side for engaging over one of the bolts 26 overlyin the strip 27 when the bolts are retracted as illustrated by dotted lines in Fig. 4 of the drawings.

Inwardly projecting floats or pins 32 having rounded ends are carried by spaced channel bars 33 longitudinally secured within the drum 12 adjacent the foraminous wall 28, these floats 32 being designed to carry the bags around with the rotation of the drum 12 until the bags drop off of the floats which causes the cement or other particles to fall from the bags through the foraminous wall 23 into the hopper 33 forming the base of the casing 10. A door 8% is provided for the hopper 33 in the front wall of the casing 10 for removing the particles cleaned from the bags in the manner described.

The sheet metal formation of the casing 10 and the complete arrangement thereof as well as the drum 12-will be apparent from this detail description. The bags are first placed into the drum 12 and the door 22 are sufficiently cleaned, when the motor 13 i 12 being formed of sheet/metal aflord re- 7 is stopped and the doors 11 and 22 opened for removing the bags from the drum 12 and the matter collected from the bags may be removed at any time from the'hoppe'r 33 by opening the door 3 1. By the conserving of the bagged commodity, the operator of the invention saves] a valuable quantity thereof asvvell as insuring the cleaning of the bags easily and quickly, the doors 11 and 34 of the casing 10being dust tight so phat the operation of the invention is dustess. be

While the form of the invention herein set forth is believed preferable, it Will be understood that minor changes may be made therein without departing from the spirit and scope of our invention.

The circular ends or heads 14 of the drum siliency to the structure permitting vibration as the bags drop upon the foraminous wall 23.

Angle irons and channel bars are em ployed throughout thestructure and the floats 32 Within the channels 33 may be of desired size such as considerably resupport ng casing, aforaminous drum trunnioned axially of said casing, means for rotating said drum exteriorly of the casing, channel bars secured by'the opposite ends of the opposing faces of the end Walls of said drum in spaced relation interiorly thereof, inwardly projecting floats secured by one of their ends to the channel bars and adapted for engaging the bags when the drum is in operation.

In testimony whereof We aliix' our signa tures;

JOSEPH C. FULKERSON. LE ROY B. STUART. 3
